Rose plant Jacsil

ABSTRACT

A floribunda rose variety having unusual pale lavender color (near silver) coupled with attractive dark green foliage, few prickles, high cut flower production and a vigorous upright habit of growth.

This present invention relates to a new and distinct variety of roseplant of the floribunda class which was originated by crossing anunnamed variety with the variety Angel Face, U.S. Plant Pat. No. 2,792.

The primary objective of this breeding was to produce a new rose varietyof a lavender color suitable for use as a greenhouse cut flower. Thisobjective was substantially achieved along with other desirableimprovements as evidenced by the following unique combination ofcharacteristics which are outstanding in the new variety and whichdistinguish it from its parents as well as from all other varieties ofwhich I am aware:

1. Vigorous, upright and productive plant;

2. Slight, pleasing fragrance;

3. An attractive pale lavender color (75B to C) in the bud opening to anear silver color (69B to D);

4. Glossy dark green foliage; and

5. Few and large prickles.

Asexual reproduction of this new variety by budding, as performed atWasco, Calif., shows that the foregoing characteristics and distinctionscome true to form and are established and transmitted through succeedingpropagations.

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of this new variety in different stages ofdevelopment, depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar withcolor in terminology in accordance with The Royal Horticultural SocietyColour Chart except where ordinary dictionary significance of color isindicated
